Pretty much; COM extracting is a black art. Sometimes it works and sometimes it doesn't. I'll admit it, I'm not a COM god. But I keep a variety of tools at my side ( InstallShield COM extract, Heat Harvesting, OleView, InstallWatch ) and make good use of version control, build automation and lab virtualization along with some good old fashioned sluething until I get it working correctly. Then I leave it the hell alone.
Oh, and keep muttering COM sucks to developers to encourage them to use more managed code. Christopher Painter, Author of Deployment Engineering Blog Have a hot tip, know a secret or read a really good thread that deserves attention?

Not really a confidence booster, but they seem to work for the most part.
